As her popularity increased, Kazan posed for a spread in the October 1970 issue of Playboy, which was reused in Pocket Playboy #4, issued in 1974. Her appearance in the magazine opened the door for her to headline and operate two different Playboy Jazz Clubs under Hugh Hefner's oversight called Lainie's Lounge East and West on opposite coasts, one in Los Angeles and the other in Manhattan. Her Playboy photographs also inspired the look of Jack Kirby's DC Comics superheroine Big Barda.
